  具有可调结构和性质的功能性聚苯乙炔的简便合成路线

  摘要：

  使用有机enta配合物作为催化剂，以所需的收率和分子量设计并合成了五氟苯基（PFP）酯官能化的聚苯乙炔（PPAs，P 1，P 2和P 3）。此外，这些含PFP的PPA被用作前体，以通过用功能性胺取代活化的酯部分来制备一系列单官能和双官能的PPA。通过使用包括GPC，FTIR，1 H NMR，13 C NMR和19在内的多种光谱技术来表征含PFP的PPA和衍生的功能性PPA的结构。1 H NMR。实验细节和特性数据表明，活化酯合成功能性PPA的途径很容易（只需在室温下将前体聚合物与适当的胺搅拌数小时即可），效率高（已确认从酯到酰胺的完全过渡），定量的（特定官能团的相对含量可以通过控制官能胺的进料比精确设定）。通过使三个含PFP的PPA与手性胺或与手性和非手性烷基胺逐步反应，可获得一系列七个不同的侧链碳原子不对称的PPA。CD测量表明手性胺并入聚合物侧链中诱导了P 1骨架的螺旋形成。P 1-C

  A group of ferrocene-containing poly(phenylacetylene)s (PPAs) with different alkyl spacers were synthesized by using organorhodium complexes [Rh(diene)Cl](2) and Rh+(nbd)[C6H5B-(C6H5)(3)] as catalysts. With the aid of pi-pi interactions between the walls of carbon nanotubes (CNTs) and the PPA skeleton together with the ferrocene pendants, the polymer (P1, P2(5) and P2(10)) chains effectively wrapped round the shells of both single-walled carbon nanotubes (SWNTs) and multiwalled carbon nanotubes (MWNTs). The "additive effect" of the PPA skeleton and the ferrocene pendants in dispersing the SWNTs and MWNTs resulted in the generation of highly soluble hybrids. The solubilities of P1-functionalized SWNTs and MWNTs in tetrahydrofuran (THF) are up to 633 mg/L and 967 mg/L, respectively. They are much higher than the solubilities of M1-modified SWNTs and MWNTs, which are only 167 mg/L and 133 mg/L in THF. The results indicate the existence of a powerful polymer effect on dispersing CNTs. The high solubilities of the hybrids in organic solvents allowed us to fabricate high-quality and large-area films. Meanwhile, the desirable loading of ferrocene-containing PPAs onto the CNTs offered polymer/CNTs hybrids with multiple redox centers and ferrocene-featured electrochemical properties. The P1/MWNT hybrid exhibits evident optical-limiting properties. At high incident laser fluence, the optical-limiting power of P1/MWNT is higher than that of C-60, a well-known optical limiter. Thermal analyses indicate that the decomposition temperatures (T-d, the temperature at which a sample loses its 5% weight) for P1 and P1/MWNT are 342 and 346 degrees C, respectively, much higher than that for PPA (225 degrees C). Thus the attachment of a ferrocene pendant to a PPA backbone, followed by hybridization with CNTs, improved the thermal stability. Upon pyrolysis, both the polymer and the polymer/CNTs hybrid gave rise to superparamagnetic ceramics; the saturation magnetizations (M-s) of the ceramics derived from P1 and P1/MWNT are 29.9 and 26.9 emu/g, respectively. The latter datum is in the list of the best results reported for the magnetic nanocomposites obtained by the attachment of magnetic nanoparticles onto CNTs.

  ester-functionalized poly(phenylacetylene)s (PPAs, P1, P2, and P3) were designed and synthesized in desirable yields and molecular weight by using organorhodium complexes as catalysts. Furthermore, these PFP-containing PPAs were used as precursors to prepare a series of mono- and dual-functionalized PPAs by the substitution of the activated ester moieties with functional amines. The structures of the PFP-containing
